by Martin Rudalics <rudalics@gmx.at>.
ispell.el (ispell-region): Standard re-indent for better readability.
textmodes/ispell.el: Experimental support for support debugging.

 * (ispell-create-debug-buffer): Create a `ispell-debug-buffer' debug
   buffer for ispell.
 * (ispell-print-if-debug): New function to print stuff to 
   `ispell-debug-buffer' if debugging is enabled.
 * (ispell-region, ispell-process-line): Use `ispell-print-if-debug' to
   show some debugging info.
 * (ispell-buffer-with-debug): New function that creates a debugging
   buffer and calls `ispell-buffer' with debugging enabled.  This is also 
   en example of a possible way to use this system.
ispell.el (ispell-region): Do not prefix sent string by comment in autoconf mode
    
 This commit changes some of the `in-comment' ocurrences to more specific
 `add-comment', set only if comment prefix is to be added.
    
 When in comment, old code prefixed string by comment string to let ispell
 know this is part of a comment string.
    
 This is only supported in some modes. In particular, this is not supported in
 autoconf mode where adding the comment string messes everything up because
 ispell tries to spellcheck the `dnl' string header causing misalignments in
 some cases (debbugs.gnu.org: #12768).
Minor adjustments of recently-changed frame functions.

* buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
known to be a frame (we're in the FRAMEP branch).
* lisp.h (Qframep): Remove decl.  frame.h declares this.
* window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
since they're meant for Lisp fixnum values.
* nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
to keypad keys.
Restore some duplicate definitions.

This undoes part of the 2012-11-03 changes.  Some people build
with plain -g rather than with -g3, and they need the duplicate
definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
* lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
Define as macros, as well as as enums or as constants.
